This project involves a combination of field work and assessments, aerial surveys, and office tasks to complete a small instream incubation trial in the mainstem of the Nisutlin River with the intent of gathering comparative data for Chinook egg survival in Deadman Creek, Morley River and other Yukon Chinook spawning areas. In recent years, Morley River has been used as a control for Chinook restoration in the Teslin River watershed (Deadman Creek). However, previous work done on the Nisutlin River has shown that it could potentially be a better control to compare to restoration efforts in the Teslin River watershed, and, more specifically, provide more appropriate comparisons for assessing the success of incubating activities in Deadman Creek. Results of this project (wild survival) will not only be useful for this project but will also fill a considerable data gap for Yukon River Chinook and will help to inform Chinook stock restoration projects elsewhere in the Yukon River watershed, particularly those involving instream incubation.
